QUICHUANA BEZZII CERESA, 1934: 387 View in CoL

FIGURES 21 View Figures 20–22 , 23 AND 24 View Figures 23–24

Three males and six females were examined by Ceresa (1934), three males and five females of which comprise the type series. These eight specimens are deposited in MCSN. Each specimen of the type series is red-labelled as ‘cotypus’ with the letters ‘co’ crossed out. We designate a lectotype and seven paralectotypes to stabilize the name (see ‘Material examined’) .

Diagnostic features

Body extensively black; frontal triangle flat; bf = 1.3 (lectotype); basoflagellomere oval ( Fig. 21 View Figures 20–22 ); face extensively white pollinose, except for a central, short, shiny, black stripe comprising the facial tubercle; facial lateral stripes, when visible, with sparser pollinosity than that on the rest of the face; thorax without tufts of hairs, although longer hairs at NP, PAPT, and PC; scutum with PP pollinose and two medial, white pollinose stripes extending on the anterior three-quarters of the scutum, and diverging posteriorly; pro- and mesotibia red at least on the basal half; metafemur from copper red on the apical third to wholly copper red; metatibia copper red; wings extensively microtrichose, except for small bare areas in cells BM, CuP, basal area of C, and alula; terga black; tergum I only with short pale hairs; hairs on the lateral margins of terga I– II pale, relatively short, and wavy only towards the tip; male genitalia with superior lobes conical towards the apex ( Fig. 23 View Figures 23–24 ); hypandrium with lateral extensions on the apical half ( Fig. 23 View Figures 23–24 ); surstyli concave antero-apically, but rounded postero-apically ( Fig. 24 View Figures 23–24 ) .

Material examined (MCSN)

Lectotype: 1m, Brasil, Est. Saõ Paulo, S. Sebastiaõ, A.A. Barbiellini /cotypus.

Paralectotypes: Brasil, Est. Saõ Paulo, S. Sebastiaõ: 1m, A.A. Barbiellini, 11–1906 (handwritten), cotypus; 1m, A.A. Barbiellini, 491, cotypus; 1f, A.A. Barbiellini, 11–1906 (handwritten), cotypus; 2f, A.A. Barbiellini, 4–1917 (handwritten), cotypus; 1f, A.A. Barbiellini, 11–1906 (handwritten), 805 (handwritten), cotypus, Quichuana bezzii Cer. , det. L. Ceresa (species name handwritten); 1f , Brasil, Est. S. Paulõ, S. Sebastiaõ, A.A. Barbiellini (most of the abdomen lacking). On the ‘cotypus’ label of all the specimens, ‘co’ is crossed out in ink .

Range

Argentina, Brazil.

Taxonomic notes

Medium size species (10.7 mm, lectotype) with slender abdomen; Q. bezzii can be separated from the similar Q. undulatipila sp. nov. by the surface of the frontal triangle, which is flat in the former but domed in the latter; additionally, the hairs on the lateral margins of terga I–II are shorter and not so conspicuously wavy (wavy for a shorter length) than those in terga I–II of Q. undulatipila sp. nov.; the shape of the superior lobes and surstyli in the male genitalia also differ between Q. bezzii ( Figs 23, 24 View Figures 23–24 ) and Q. undulatipila sp. nov. ( Figs 65, 66 View Figures 65–66 ).
